FIELD: electricity. ^ SUBSTANCE: current stabilisation device contains the first current sensor, rectifier, filter, transformer, inverter, pulse-width modulation unit the output of which is connected to one of inputs of inverter. In addition, it includes the first, the second, the third, the fourth and the fifth analogue-to-digital conversion units, digital signal processing unit, control and visualisation control unit, switching unit, the first, the second and the third voltage sensors, energy storage unit, restricting unit, the second current sensor; at that, the above rectifier is made in the form of charger-rectifier. ^ EFFECT: providing current stabilisation of the specified frequency at stabilisation device output irrespective of oscillation frequency and shape of voltage of electric power supply, which acts at stabilisation device input; higher accuracy and energy efficiency of output current stabilisation irrespective of load conditions. ^ 5 cl, 1 dwg |
